CASEMENT-WINDOW SCREEN.

Broadly this invention relates to screens but it more especially comprehends the form adaptable in connection with windows of the easement type.

An important object of this invention is the provision of means for screening casement windows, whereby the screen is posi'- tioned immediately adjacent the easement frame. i

Another object of this invention is the provision of a 'screening unit including a frame having one or more screen sections slidably mounted therein, the said unit adapted to be mounted contiguous to the easement frame.

A further important object of this invention is the provision of means of the above character for mounting the screen directly adjacent the easement windows, designed4 to.

eliminate interference with the projecting hardware by utilizing the easement fastener' or operating handle as a seat to maintain the movable screen securely in raised or elevated posit-ion when the easement windows are closed, but permitting its return to lowered or operative position when the windows are opened.

A still further object of this invention is the provision of means for screeningcasement windows adaptable for mounting vagainst thecasement frame, thereby eliminating the necessity of screening any except `position Fig. 2 is a fragmentary horizontal or cross section of window and screens with lower screen in raised position;

Fig. 3 is a fragmentary view of the screen iframe showing the screen tracks at one 'side in elevation and' Fig. 4 is a front elevationy of one type of easement window, showing one of the operatcomprising an inte .mounted on the section 3 to eliect locking ing sashes open and movable screen section 1n lowered or operative position, and the other sash closed with the screen section in raised or elevated osition and seating on the sash operating handle.

Heretofore, the screening of casementwindows has been attended with considerable diculty, undue expense and labor, and unslghtly appearance, due to the fact, that what is known to the trade as window hardware or operating and locking mechanisms projeetinginwardly from the windows, rendered it possible to screen such windows, if at all, only by mounting the screens spaced some distance therefrom. This necessitated the attachment of strips to the sill faces or jambs interiorly of the room thereby'marring the woodwork and necessitating the use of a screen larger in area than the easement opening, and it was to overcome such deficiencies by providing a means for screening easement windows, whereby the anchoring strips would be eliminated, the amount of screening material substantially reduced, and necessitating the screening only of the -aetually operating easement sash sections, that I designed-the screening device forming the subject matter of this invention.

In the illustrated embodiment characterizing this invention there is shown a casement window or frame designated generally by the numeral 1, and in the present instance al top section 2 and vertical central section 3, operating hinged sections or sashes 4 and 5, respectively, each ofl which carries an operating handle 6 adapted to cooperate with a wedge plate o the hinged sections when in closed position, and an adjustable means 8 suitably secured to each of the movable sashes and to the easement frame to lock said sashes in any desired open position. The sections 2, 3, 4, and 5, are formed with glass panels 9 of well lknown construction.

A square or rectangular metal frame. 10

corresponding' substantially to the size of l the hinged sections 4 and 5, or the opening to be screened, is formed with top and bote tom transverse members 11 and 12, respectively, and extending outwardl at right angles from the ends of said mem ers 11 and 12 are the vertical side members 13, the outer or free edges of which are adapted to be folded back upon'themselves to form vertically extending ribs or tracks 14 for a purpose which will presently more fully appear. Welded or otherwise suitably secured to the inner surfaces of members 13 are the metal strips 15 having their free edges folded back upon themselves, similar to the sides 13, to form tracks 16 extending parallel with and slightly spaced from the tracks 14.

A screen section 17 normally screening the upper portion of frame 10 is slidably mounted on the tracks 16, and a corresponding screen section v18 is similarly mounted on the tracks 14 and normally adapted when operatively positioned to screen the lower portion of said frame 10. In order to conveniently raise and lower the slidable section 18 one or more handles 19 are suitably Secured to the bottom thereof. Suitably secured to the top of frame 10, as at 20, is a slotted slidable hook orgrip member 21, which when in extended position is adapted to hold or maintain the lower screen section 18 in raised or elevated position while the easement sash is open, when it is so desired.

It will be noted that the screening unit comprising the frame 10 and screen sections 17 and 18 mounted therein is adapted to be placed over the opening to be screened and secured to the easement frame 1 by bolts or screws 22, thereby effecting a unitary structure of easement and screen. Thus it is evident, that to install the screens it is only necessary to position the frame 10 against the easement frame 1 and insert the screws 22. To remove the screening unit the said screws are merely withdrawn, and when reinserted in the frame 1 the pleasing appearance of the interior surface of the easement is preserved, Without leaving unsightly evidence of the removal of the screens as has been prevalent in connection with the manner of screening easement windows heretofore in use.

lAlso manipulation of the movable screen section incident to each operation of opening and closing the easement window section or sash is greatly reduced by the employment of my device, since, as illustrated in Fig. 4 of the dnawings, when it is desired to open, for instance, the sash 5, it is only necessary to actuate the handle 6, push open the sash and allow the screen section 18 to drop to operative'position, as shown in Fig. 4 when sash 4 is open. To close the casement, the screen section is raised by the handle or lift 19, the sash broughtl to closed position, and the handle 6 agam moved to locked position, whereu on the screen section remains in such e evated osition by seating on said member or han le 6, as in the first instance. y

From the foregoing it is apparent that I have not only effected the expeditious screening of easement windows, by providing a structure of simplified construction, economical of manufacture, and susceptible of expeditious installation without in any manner marring the normal appearance of the interior finish of the window or jambs, but I have overcome the heretofore baffling interference of the easement sash operating and locking means or handle with the screen, While at the same time. utilizing said handle as a seat for coaction with the screen to reduce the operations and labor incident to the opening and closing of the easement sashes when screens are employed in connection therewith. v

Although in practice, I have found that the form of my invention illustrated in the accompanying drawings and referred to in the above description as the preferred embodiment is the most efficient and practical; yet realizing that ythe conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize that various minor changes in details of const-ruction, proportion and arrangement of parts, may be resorted to within the scope of the appended claims without departing from or sacrificing any ofthe principles of this invention.

Having thus described my invention, what I desire protected by Letters Patent is as set forth in the following claims:

1. The combination with a easement window, of a frame conforming to the contour of the easement window sills, means to aix the frame at its opposite ends to thefsills, a pair of screens slidably mounted in the frame and adapted when extended to completely screen the easement opening.

2. The combination with a easement window including its Window sections or sashes, of a pair of longitudinally adjustable screen members, and means for associating said members with the window easement so as to permit operation of its window sections.

3. The combination with a window casement, its hinged window section including a latch or operating handle, of a frame including a pair of slidably movable screens, said screens when in extended position completely screening the frame, one of said screens a'dapxted when in raised osition to seat upon t e latch handle of t e window section.

5. The combination with a window casement, its hinged sash and sash operating handle, of a frame including a pair of slidably movable screens, said frame being secured to the easement, the screens when in extended position completely screening the fraine.l one of said screens being maintained `irl-,elevated position by the sash operating handle when said sash is in closedposition.

6. The vcombination with a window casement, its hinged window sashes including v sash operating handles, of a frame secured to the easement embodying parallel side and top members, a pair parallelly movable screens slidabl connected with the side members and w en in extended position completely screening the frame, one of said screens adapted to seat on the operating handles when the sashes are in closed position, and to return to lowered position when 2o the sashes are open.
